Question 4 of 5

Mathematics
2 answers:
Alex777 [14]3 years ago

Answer:

B

Step-by-step explanation:

For example, if solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.

I hope it helps.

The areas of the four sectors of the spinner are equal.The probability of spinning C and tossing a head with a penny is show wor
frozen [14]
Since the 4 sectors of the spinner are equal, the probability of spinning any one of them is 1/4. Coins are always 50/50, so the probability of tossing a head with a penny is 1/2. Since the question is spinning C AND tossing a head with a penny, you must multiply the two previously found probabilities. 1/4 times 1/2=1/8 so 1/8 is the answer.

How many square tiles of side 10cm each will be needed to tile a floor which is 300cm long and 150cm wide?
S_A_V [24]

Step 1

Find the area of one tile

we know that

the area of a square is

A=b^{2}

where b is the length side of the square

In this problem

b=10\ cm

Substitute

A=10^{2}=100\ cm^{2}

Step 2

Find the area of the floor

The area of a rectangle is equal to

A=LW

where

L is the length of the rectangle

h is the width of the rectangle

In this problem

L=300\ cm

W=150\ cm

Substitute

A=300*150=45,000\ cm^{2}

Step 3

Find the number of tiles needed

by proportion

\frac{1}{100} \frac{tile}{\ cm^{2}} =\frac{x}{45,000} \frac{tile}{\ cm^{2}} \\ \\x=45,000/100 \\ \\x=450 \ tiles

therefore

<u>the answer is</u>

450 \ tiles
